Given numbers are 165,551,837,957
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 165,551,837,957 is 25365285.
Find LCM of 165,551,837,957 with Prime Factorization
| 3 | 165, 551, 837, 957 |
| 11 | 55, 551, 279, 319 |
| 29 | 5, 551, 279, 29 |
| 5, 19, 279, 1 |
Multiply the prime numbers at the bottom and the left side.
3 x 11 x 29 x 5 x 19 x 279 x 1 = 25365285
Therefore, the lowest common multiple of 165,551,837,957 is 25365285.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
165 x 551 x 837 x 957 = 72823733235
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
165 : 1, 3, 5, 11, 15, 33, 55, 165
551 : 1, 19, 29, 551
837 : 1, 3, 9, 27, 31, 93, 279, 837
957 : 1, 3, 11, 29, 33, 87, 319, 957
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 165,551,837,957, is 1.
Now, the common factors can be found like this.
165:3x 5x 11
551:19x 29
837:3x 3x 3x 31
957:3x 11x 29
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 11x 29 = 2871
Therefore, the value for common factors is 2871.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 72823733235/(1x2871)
LCM = 72823733235/2871
LCM = 25365285
Thus, we can understand that the LCM of 165,551,837,957 is 25365285.
